Scale effect on bearing capacity of shallow foundations on strain-softening clays
نویسندگان
چکیده
Progressive failure is common in many natural clays of strain-softening behavior and may affect the bearing capacity foundations placed on such soils. The progressive might be insignificant for small structures where mobilized strains are generally uniform within failed soil mass. This places a demerit to applications knowledge obtained from physical model tests prototype. study aims understand quantify this scale effect shallow clays, with numerical investigation using large deformation finite element analysis. numerically replicated controlling parameters have been discussed. A correction factor introduced which inversely proportional foundation size normalized by proposed characteristic length. An empirical relationship has via data, improve design clays.

The Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations
Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...
متن کاملBearing Capacity of Shallow Foundations on Cohesionless Soils: A Random Forest Based Approach
Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...
